MS Position in Agroecology: Cover Crops in the Southwest: Obtaining Ecosystem Services While Minimizing Water Use New Mexico State University, Las Cruces, NM
Project Summary: The agroecosystem services provided by cover crops, including enhanced soil health, erosion prevention, carbon sequestration, nutrient provision and pest management, are widely recognized. Nonetheless, in arid environments the benefits received from cover crops must be balanced with their water consumption. Growers in the Southwestern USA desire the benefits of cover crops, but are concerned about the impacts of irrigation requirements on economic returns. Thus, we are conducting a study focusing on minimizing irrigation needs while still obtaining cover crop agroecosystem services. Using three cover crop species plus a three-way mixture under four irrigation regimes, we will assess impacts to a suite of characteristics including soil organic matter, aggregate stability, nutrient availability, and the rhizosphere microbiota including nematode, bacterial and fungal communities. Further, we will assess fungal disease, weed pressure and impacts to productivity and profits.
We are seeking an outstanding MS student to conduct research on the microbial component of this study: i.e., nematodes, bacteria and fungi. Research will be under the direction of Drs. Pietrasiak (Plant and Environmental Sciences, https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Faces.nmsu.edu%2Facademics%2Fpes%2F&data=02%7C01%7Cmiranda.l.davis%40uconn.edu%7Ce6fdcc48a56248351aa908d65f650873%7C17f1a87e2a254eaab9df9d439034b080%7C0%7C0%7C636801284868800938&sdata=BER%2Fkewpi0wpDYOU1R8PIotM4o1KOMQ4QPyZIGaNFoc%3D&reserved=0) and Lehnhoff and Sanogo (Department of Entomology, Plant Pathology & Weed Science,https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Feppws.nmsu&data=02%7C01%7Cmiranda.l.davis%40uconn.edu%7Ce6fdcc48a56248351aa908d65f650873%7C17f1a87e2a254eaab9df9d439034b080%7C0%7C0%7C636801284868800938&sdata=W0W5BWKlIe%2F4Z5jk0fVxfJsmx%2BPOdfjEsZssdNIRffs%3D&reserved=0. edu/).
